q2 i? The Graphical Jogthrough method produces evidence as a graph presenting the estimated proportion of users who effectively use the interface against the time they had to work with it to succeed in effectiveness. → Stavros Demetriadis 1999

Evidence¶

Stavros Demetriadis 1999¶

Stavros Demetriadis, Athanasios Karoulis, Andreas Pombortsis. (1999). “Graphical” Jogthrough: expert based methodology for user interface evaluation, applied in the case of an educational simulation interface. Computers and Education. https://telearn.hal.science/hal-00197391

q2 · i? · design · r2

Definitional statement of the method’s output as described in the article: evaluators’ ratings are transformed into a graphed curve of “estimated proportion of users who effectively use the interface” versus time. No effect size is printed.

"Graphical Jogthrough is a further modification of a typical Jogthrough method, where evaluators' ratings produce evidence in the form of a graph, presenting estimated proportion of users who effectively use the interface versus the time they had to work with it in order to succeed effectiveness."
